SIP SRST dual line

[Glenn Martindell]

Feel like I should know the answer to this, but I cannot find any Cisco docs with the answer.  Does anyone know if I can have SIP phones register in SRST and be able to take multiple calls on a single DN simultaneously using SRST default mode or do I need to use ESRST or CME-SRST?   If so, what is the command to make this happen?   I just implemented default mode SRST and my SIP phones give a busy when the 2nd call comes in.

Thanks in advance,

Glenn

Hi,

You need CME SRST to get multiple lines/DNs configured in your SRST
gateway. Check your busy-triggers and max lines configured under your DNs.

Hi Mohammed,

Thanks for the reply.  I tried the busy-triggers setting but I can still only get a single call to a DN at a time.  So that didn't seem to do anything for me.  It seems odd to me that in basic SRST mode I can only get a single call to a DN for SIP phones but I can set SCCP phones to dual or octo.

Thanks,

Glenn
